Fetal radiation exposure is minimal after pelvimetry by modified digital radiography

Article Abstract:

There appears to be minimal radiation exposure to the fetus during digital radiographs particularly when using a modified angle. Digital radiographs are used to measure the mother's pelvis during pregnancy to help predict the practicality of a vaginal birth. Doctors performed digital radiographs on 29 pregnant women to evaluate the radiation exposure to the fetus. Standard digital radiographs resulted in a maximum of 465 millirads (mrad) to the fetus. Modifying the radiograph angle resulted in a substantially lower exposure (55 mrad).

Pharmacokinetic and fetal cardiovascular effects of enalaprilat administration to maternal rhesus macaques

Article Abstract:

Enalapril may produce potentially dangerous effects in the fetus. Enalapril is a drug used to treat hypertension, including hypertension during pregnancy. Researchers measured the effects of a metabolite of enalapril called enalaprilat in five pregnant rhesus macaques and their fetuses. The drug readily crossed into the fetal circulation where it significantly decreased arterial blood pressure. Arterial blood pressure remained depressed throughout the six-hour experiment.

Outcome of cardiovascular surgery and pregnancy: a systematic review of the period 1984-1996

Article Abstract:

Heart surgery on pregnant women can lead to substantial complications and even death for both mother and baby. A review of heart surgeries on 161 pregnant women between 1984 and 1996 revealed mortality rates of 30% among the babies and 6% among the mothers. The rate of complications and death was greater if the surgery was performed close to delivery. Pregnant women appear to have a greater risk of death or complications from heart surgery than non-pregnant women.
